Water drainage system with angle and space of nozzles capable of being adjusted

Abstract

The invention relates to a water drainage system with the angle and space of nozzles capable of being adjusted. The water drainage system comprises a plurality of spraying pipes, a spraying pipe sliding rack, spraying pipe transverse limiting racks, spraying pipe angle adjusting racks and water segregators. The multiple spraying pipes are arranged on the spraying pipe sliding rack side by side and are positioned through the spraying pipe transverse limiting racks. Each spraying pipe is provided with the multiple nozzles in the longitudinal direction. The liquid inlet end of each spraying pipe is connected with the corresponding water segregator through a hose, and each water segregator is connected with an external high-pressure quenching liquid conveying pipeline. The closed ends of the spraying pipes are fixedly connected with the spraying pipe angle adjusting racks and make the spraying pipes rotate around the axes of the corresponding spraying pipes under the driving action of the spraying pipe angle adjusting racks. The water drainage system is used for obtaining reliable experimental data of the structure condition of steel plates of different materials and thicknesses after quenching under the quenching experiment condition of the angle and space of different sorts of spraying liquid; and it is of great significance to providing an effective reference base for intensively studying the quenched structure phase change law and mechanism, formulating quenching technological parameters for industrial batch production and improving product quality.

Description

technical field [0001] The invention relates to the technical field of metal heat treatment, in particular to a water drainage system with adjustable nozzle angle and spacing for steel plate liquid spray quenching experiments. Background technique [0002] At present, the heat treatment process of obtaining high-performance steel plates by spray quenching or immersion quenching is widely used in various industries. Due to the adverse effects caused by the uniformity of the structure, etc., in the prior art, high-pressure liquid spraying water discharge is often added in the quenching tank, and the steel plate is immersed and the high-pressure liquid spraying is carried out through the nozzle with a certain spraying angle and spacing. . [0003] For steel plates of different materials and thicknesses, the spray angle and nozzle spacing should also be set accordingly; however, there is no accurate standard for the setting of such parameters as a reference at present, and it c...

Problems solved by technology

[0003] For steel plates of different materials and thicknesses, the spray angle and nozzle spacing should also be set accordingly; however, at present, there is no accurate standard for the setting of such parameters as a reference, and it can only be set by the experience of scientific researchers, resulting in different materials and nozzles. The quenching effect of high-temperature steel plates with different thicknesses on the same quenching equipment or high-temperature steel plates of the same material and thickness on different quenching equipments produces large fluctuations
